At 3:09 p.m. Thursday Cayuga County 911 received a report of a suicidal person who possibly had firearms. Deputies and state troopers responded to the scene at Thompson's Poplar Cove home on the shore of Owasco Lake. As they arrived, they encountered Thompson outside his home, armed with a shotgun, the sheriff's office said.

Thompson fired the shotgun once and retreated into his home, the sheriff's office said. More police arrived and a standoff began. Negotiators from the sheriff's office managed to establish communication with Thompson.

During negotiations, which lasted several hours, Thompson fired three more shots -- from inside and outside his home, the sheriff's office said. He also came out of his home several times, sometimes with and other times without the shotgun.

But he retreated back into his home each time, the sheriff's office said.

At around 8:15 p.m., Thompson came out of his home unarmed again and a "less lethal" device was used to temporarily incapacitate him, the sheriff's office said. Authorities did not specify what type of device was employed.

An arrest team made up of deputies, and SWAT teams from the sheriff's office and Auburn police took Thompson into custody. He was taken to Upstate University Hospital in Syracuse for treatment of non life-threatening injuries received during the arrest, the sheriff's office said. He will be arraigned after he is released from the hospital.

Deputies are continuing to investigate and expect to file more charges against Thompson, the sheriff's office said.
